SEAL.-

GPECIFICTION forming part of Letters Patent No. 323,849, dated August 4, 1885.

(X0 model) To all whom it may concer'n:

Be it known that I, EDWARD J. BRooKs, a citizen of the United States, residing at East Orange, in the State of New Jersey, have invented a new and useful Improvement in Seals, (VZ) of which the following is a specification.

My present invention belongs to improvenients in those press-fastened seals each of which is composed of a flexible shackle of Wire and a seal-disk of soft metal, preferably lead, adapted to embrace the shackle ends and to be solidified around them to fasten the seal. To prevent the withdrawal of either shackle end without such mutilation or defacement of one of the parts as would leadto detection, 4' auchoring77 devices on the shackle end or in the Seal-disk are essential in most seals, and have been heretofore formed in various ways.

In common With my inventions set forth in United States Patents No. 179,260, dated June 27, 1876, and No. 192,735, dated July 3, 1877, the general object of my present invention-is to provide single shackle-Wire with effective anchoring or withdrawal-resisting devices in such a way that they serve additionally as detector77 devices to indicate genuine shackles, and thus prevent or insure the detection of any substitution of a new shackle for one that has been broken in tampering With a seal.

The special objects of the present invention are, first, to produce a very light detector- Wire, more secure than Cable-Wire, and adapted to be more cheaply produced than either of those styles set forth in said Patents No. 179, 260 and No. 192,735; and, secondly, to prodnce, with the aid of such Wire, a superior thin and cheap cast-in7 seal.

This invention consists, first, in a hard-metal shackle of fine single Wire, provided with permanent sharp bends in a single plane, forming zigzag withdrawal-resisting surfaces, in combination With a soft-metal seal-disk embracing or adapted to embrace the same; and, secondly, in a cast-in seal composed of a softmetal Seal-disk having a single threading-hole,

'and a hard-metal shackle of light single Wire having a straight end provided with a bentup anchoring enlargement cast fast in the sealdisk, and a zigzag threading end to occupy said threading-hole, as hereinafter more fully set forth.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 of these drawings is an elevation of the shackle and Seal-disk of my said cast-in sea-l, straight, as it leaves the factory, the sealdisk being shown in dotted lines to expose the anchoring device of the cast-in shackle end. Fig 1Z shows magnified face and end Views of its zigzag threading end. Fig. 2 is a face view of the seal applied to a pair of cardoor staples and ready for the Seal-press. 3 represents a like View thereof pressed and Figs. 4 to 8, inclusive, represent modifications of the shackle, as hereinafter described.

'Like letters of reference indicate corresponding parts in the several figures.

A represents the shackle, B the seal-disks, and O O a pair of car-door staples, the separation of which is prevented or manifested by the pressed seal, Fig. 3. The shackle A, in either of its forms, is of fine (thin) or relativelyfine Wire of hard metal, preferably iron, 'provided with permanent sharp bends in a single plane, forming short rigid withdrawal-resisting portions'at opposing angles, or zigzag at Fig.

one or each end, z, of the shackle.r (See Fig.

12.) These shackle ends z are adapted to be readily threaded through thin seal-disks, to hold effectively in the pressed-seal disk without change of form, and to manifest the genuineness or fraudulency of shackles found in' the seals of roads using this invention.

' In the preferred species represented by Figs. 1, 2, and 3, and in those modifications thereof represented by Figs. 4 and 5, the shackle A has one zigzag77 threading end, z, and at its other extremity a straight end, a, provided with a bent-up anchoring enlargement, b, like those set forth and claimed in said ?atent No. 192,785. So constructed, this end is adapted to be inserted in a Seal-disk mold, so that the.

vided with a threading-hole, lz, Fig. 1, to rooeive the zigzag threading end z. After passing said threading end z through the staples O O or the like, it' is threaded through the Seal-disk, as represented by Fi. 2, and the latter is then pressed, and in this aot provided With lettering or other distingnishing marks, d, as represented by Fig. 3. T'ne improved seal shown in this fignre is pressed by means of my roller Seal-press, patented June 2,1885. The zigzag eonstrn etion, adapted to be extended in length as far as may be desired with little or no additional cost, readers these improved seals peenliarly Well adapted for use in connection with said Seal-press.

In said modifications, represented by Figs. 4 to 8, inclusive, the fineness of the Wire and the shape and extent of the sharp angular bends vary Without departing from the construction, mode of operation, and advantages hereinbefore set forth.

Those shaekles represented by Figs. 6, 7, and 8, each having two of' the '/,igzag ends z, are especially designed for use in seal-disks having' pairs of threadng-holes, examples of which are shown in said Patents No. 179,260 and No. 192,735.

Having thns deseribed my said improven'ient in seals, (V) I elaimias my invention, and desire to patent, under this specificationl. In combination with a soft-metal sealdisk, a deteotor-shaekle of fine single Wire, of hard metal, having permanent sharp angnlar bends in a single plane, forming short rigid Withdrawal-resisting portions at op posi ng angles, or zigzag, as herein speeified, for the purposes set forth.

2. The within-desoribed improved seal, comprising a fine single Wire ofhard metal, having a zigzag threading end formed by permanent sharp bends in a single plane, and a straight end provided With a bent-up anehoring enlargement, in combination with a soft-metal sealdisk east fast on said straight end around said anchoring enlargement, and having a threading-hole to receive said threading end, snbstantially as herein speeified.
